Mr. Spears... just grasping for a straw here... inspect the lifters (tops) while the intake is off. Probably all is well but,the "stuff" had to come from somewhere!

And purely as a PM task, I'd replace the dizzy drive gear pin. It's taken a nasty hit imho... needs to be changed. fwiw..

Mike,
That's a good call on the lifters. When I was talking to Scott he went over and picked up a lifter that he'd just taken out of a 302 and he suggested the same thing, look at the tops and be sure that the little spring clip is in place on all of them. Well, recall last year I had the roller pin come out of the end of my #1 exhaust rocker, and that roller bounced around and tangled with the #1 intake and that one snapped in half? Well, the spring retainer in #1 exhaust was gone, and that's the wire in the pan. Also, that "spacer" which measures 0.390"/0.290" x 0.050" thick is very likely off of the pump drive shaft, or is a "shim" in either the bottom of the distributor or the top of the oil pump. Regardless, I'm pretty sure that it's off of the broken shaft.

I also put a dial indicator on the oil pump, and the outer element ran with zero distortion (as would be expected), but the inner shaft driven element has between four and five thousandths of runout, showing that the shaft is bent which contributed to the twisted shaft.

And on a "bad things happen for good reasons" sideline, I noticed this morning that on the drivers side intake bank the intake gasket had small tears at the corners of two adjacent ports, one to the valley, and one to ambient so I've likely been losing vacuum for some time.

Headed to get parts now....
